<p>Provided is a manufacturing method for nonwoven fabrics that enables the manufacture of nonwoven fabrics exhibiting excellent strength, bulkiness, and flexibility. This manufacturing method for nonwoven fabrics includes: a step in which a papermaking raw material containing moisture is supplied onto a support body (16) to form a paper layer (23) on the support body (16); and a step in which a steam nozzle (14) is used to spray high-pressure steam onto the paper layer (23). In the step in which the high-pressure steam is sprayed onto the paper layer (23), the high-pressure steam is sprayed onto the paper layer (23) after the moisture content of the paper layer (23) is adjusted to 10-45%.</p>
